+
+Tue Jul 4 08:47:35 2006 Ben Pfaff <blp@gnu.org>
+
+ Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
+ ALL) and additional underlying system file issues.
+
+ Thanks to John Darrington for review.
+
+ First problem: var_hash points to variables not owned by the
+ sys-file-reader, which the caller may free or modify. Use an
+ array of sfm_vars instead, as done earlier (e.g. CVS version
+ 1.12).
+
+ * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
+ members and remove all code that references it. Add vars, var_cnt
+ members. Remove fix_specials member, which was unused.
+ (struct sfm_var) Remove name member, which was unused.
+ (sfm_close_reader) Free vars member instead of var_hash.
+ (compare_var_shortnames) Removed.
+ (hash_var_shortname) Removed.
+ (sfm_open_reader) Fill out vars array.
+ (compare_var_index) Removed.
+ (sfm_read_case) Use vars instead of var_hash.
+
+ Second problem: we're confused about when we actually have very
+ long strings, causing us to choose incorrectly between slow path
+ and fast path in sfm_read_case.
+
+ * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
+ have very long strings, not when we have long variable names,
+ which is an unrelated feature.
+
+Tue Jun 27 12:06:49 2006 Ben Pfaff <blp@gnu.org>
+
+ * variable.h: Move var_set and variable parsing declarations to
+ new header, src/language/lexer/variable-parser.h. Modified lots
+ of files to include the new header.
+
+Sun Jun 25 22:39:32 2006 Ben Pfaff <blp@gnu.org>
+
+ * value-labels.c (value_to_string): When there's no value label,
+ format the variable according to its print format, instead of

+Sat May 6 22:46:47 2006 Ben Pfaff <blp@gnu.org>

+
+Sat May 6 13:37:52 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution.

+ references.
+ (static var vfm_sink) Rename proc_sink. Update all references.
+
+Sat May 6 12:38:55 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. In this phase, remove
+ PROCESS IF, which was deprecated anyway and can be easily
+ simulated with TEMPORARY followed by SELECT IF.
+
+ * procedure.c: (open_active_file) Don't call
+ add_process_if_trns().
+ (discard_variables) Get rid of redundant call to
+ proc_cancel_all_transformations().

+Sat May 6 10:30:33 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. In this phase, get rid of
+ the output code for SPLIT FILE groups in procedure.c, which really
+ shouldn't be doing any output. Move it into the individual
+ procedures instead. This also adds some flexibility.
+
+ Updated many users of procedure_with_splits() and
+ multipass_procedure_with_splits() to call
+ output_split_file_values() and to deal with increased use of
+ const.

+ outputting case.
+ (multipass_split_output) Pass saved SPLIT FILE case to split_func.
+
+Fri May 5 22:48:50 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. Change
+ internal_procedure() so that it calls open_active_file() and
+ close_active_file(), which isolates most of the actual procedure
+ functionality.
+
+ * procedure.c: (struct write_case_data) Rename `proc_func' member
+ to `case_func' and update all references.
+ (procedure) Rewrite as one-line wrapper around
+ internal_procedure().
+ (struct multipass_aux_data) New.
+ (multipass_callback) Renamed multipass_case_func(). Use struct
+ multipass_aux_data as auxiliary data.
+ (multipass_end_func) New function.
+ (multipass_procedure) Rewrite as wrapper for internal_procedure()
+ that uses multipass_case_func, multipass_end_func.
+ (internal_procedure) Add `end_func' argument. Move optimization
+ of trivial case in here. Move call to open_active_file() and
+ close_active_file() in here. Now assert that vfm_source is
+ non-null.

+
+Thu May 4 21:50:11 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. In this phase, move
+ procedure.c and procedure.h from src to src/data. Update
+ makefiles and #includes accordingly.
+
+ * procedure.c: Moved here from src/.
+
+ * procedure.h: Moved here from src/.
+
+Wed May 3 22:42:12 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. In this phase, get rid of
+ many global variables, consolidating procedure execution in
+ procedure.c. Encapsulate transformations in new "struct
+ trns_chain". Also, change implementation of N OF CASES, FILTER,
+ and PROCESS IF from special cases to transformations.
+
+ * automake.mk: (src_data_libdata_a_SOURCES) Add transformations.c,
+ transformations.h.
+
+ * dictionary.c: (global variable default_dict) Move to
+ src/procedure.c.

+
+ * storage-stream.c: Add missing function comments.
+
+Tue May 2 15:50:21 2006 Ben Pfaff <blp@gnu.org>
+
+ Continue reforming procedure execution. In this phase, add some
+ new, needed functionality to storage-stream.
+
+ * storage-stream.c: (storage_source_decapsulate) New function.
